摘要
微电网对于减小分布式电源接入对配电网的影响,提高供电可靠性和电能质量具有重要的意义。首先介绍微电网的基本结构和分类,然后从理论分析的角度阐述智能微电网的供电模式,并进一步提出适用于户用微电网的调、配、用一体化的综合监控平台系统设计和设备选型原则。结合草原上风能与光伏资源的分布情况,设计应用于实际工程的典型供电模式,并根据实际情况对各种分布式电源的容量进行优化配置,其对于户用型微电网的建设具有一定的指导意义。
Micro-grid is a promising concept that is considered as an alternative solution for reducing the influence of integration of distributed generation into distribution system and improving power supply reliability as well as power quality. The basic structure and classification of micro-grid are introduced firstly. Then, the typical power supply mode of micro-grid is proposed from the perspective of the theoretical analysis. Furthermore, the systematic designing schemes and equipments selecting principle of the integrated supervisory control system of the home micro-grid are presented. The typical power supply mode which is applied to practical engineering is designed combining with the distribution of wind and solar power in the prairie area. The optimal capacity of distributed generations is also analyzed according to the actual demand. The result of this paper can be used to guide the construction of the home micro-grid.
